First we need to know the coordinates of the movie theater, we can do this applying the midpoint formula:

We have that the movie theater is located at (2,4). Now we use this coordinates to find the location of Clara's house using again the midpoint formula:

Therefore, Clara's house is located at (-2,0)
X^2+x+8 is the answer unless you need it factored
Step-by-step explanation:
a is the correct not sure though

By the fundamental theorem of calculus, the first derivative is

and so the second derivative would be

which means
